It's not uncommon for fringe draft prospects to speak with teams about free-agent deals while the draft is in progress. Former Michigan defensive lineman Ryan Van Bergen took that path last year, signing with an NFL team just moments after the draft concluded.

Van Bergen's team: The Carolina Panthers.

Roh, Van Bergen's linemate at Michigan, followed that path as well and will compete for a roster spot in rookie camp. He started 51 games for the Wolverines, a school record, and recorded a unit-high four sacks last year.

Expect to see more Michigan players sign free-agent deals in the hours and days ahead. Safety Jordan Kovacs is the best candidate, followed by receiver Roy Roundtree, offensive lineman Patrick Omameh and linebacker Kenny Demens.
